Overview
Mucoprom Syrup is a syrup with Promethazine Hydrochloride declared as its active content. It is supplied in a pack size of 120ml.
This is a non-prescription product and can be purchased without a prescription. Only product, safety and handling details are published on this page.
An online consultation with a DoctorOnCall doctor or pharmacist is available for this product, and a registered pharmacist reviews each order before dispatch to Malaysia or Singapore. Follow the directions on the label and on the leaflet inside the pack.
Directions for Use
Shake the bottle well before each use and measure the dose using the measuring cup or spoon provided rather than an ordinary household spoon. Mucoprom Syrup may be taken with or without food, and because it commonly causes drowsiness, it is often best taken in the evening or before bedtime unless your pharmacist or doctor advises otherwise; avoid alcohol and do not drive or operate machinery until you know how the syrup affects you.
Dosage
Dosing is based on age and should follow the product label or your pharmacist’s or doctor’s advice, as promethazine syrup is generally not recommended for children under 2 years of age due to the risk of severe breathing problems. Adults and older children are typically given a measured dose every 4 to 6 hours as needed, without exceeding the maximum daily amount stated on the packaging, and the lowest effective dose should be used for the shortest time needed to control symptoms.
Shelf Life
Mucoprom Syrup remains effective until the expiry date printed on the bottle and carton when stored correctly and unopened. Once opened, check the label or ask your pharmacist for the recommended in-use period, and discard any syrup that has changed in colour, smell, or consistency even if the printed expiry date has not yet passed.
Storage Instructions
Store Mucoprom Syrup below 30°C in a cool, dry place away from direct sunlight and moisture, and keep the bottle tightly closed after use. Do not refrigerate or freeze unless the label specifically states otherwise, and keep the syrup out of reach and sight of children at all times.

Relevant Information
Mucoprom Syrup is sold as a non-prescription pharmacy medicine in Malaysia for short-term relief of dry cough and allergy-related symptoms, but because promethazine causes significant sedation and is not suitable for very young children, it is advisable to check with a pharmacist before giving it to children, the elderly, or anyone already taking other sedating medicines.

Within Malaysia, standard delivery takes 3 to 5 working days. Same-day delivery is available in the Klang Valley for orders placed before 12pm; orders placed after 12pm arrive by the end of the next day.
Orders to Singapore are sent as international deliveries and take 5 to 9 working days. A lump-sum shipping and handling fee applies to every overseas delivery and is shown at checkout.
Customers in Malaysia can pay by FPX online banking, credit or debit card (Visa and Mastercard), and supported e-wallets including Touch ‘n Go eWallet, GrabPay and ShopeePay.
FPX and local e-wallets are tied to Malaysian bank and wallet accounts, so if your delivery address is in Singapore, use the payment options displayed at checkout for that address rather than assuming the same list applies.
Yes. DoctorOnCall ships to Singapore as an international order dispatched from Malaysia, arriving in 5 to 9 working days with a lump-sum shipping and handling fee.
Singapore’s Health Sciences Authority (HSA) allows personal imports of up to three months’ supply of a medicine for your own use or an immediate family member’s, as long as it contains no controlled drugs, psychotropic substances or prohibited items. Keep the product in its original labelled packaging and keep a copy of your prescription or doctor’s letter with it. Quantities above three months’ supply, and medicines containing controlled substances, require prior HSA approval.
Products listed on DoctorOnCall are registered with Malaysia’s Ministry of Health for supply in Malaysia, and each pack carries its MAL registration number.
An order delivered to Singapore arrives as a personal import of a Malaysia-registered product; HSA product registration is not required for personal-use quantities, but it is also not the same as a product registered for sale in Singapore. If you need a locally registered Singapore product, buy it from a pharmacy in Singapore.
DoctorOnCall’s customer care team handles order, delivery and product queries through the contact channels on the site, including WhatsApp and the online help centre.
For deliveries to Singapore, allow more time before chasing an order than you would for a local Malaysian delivery, as the parcel passes through customs clearance and tracking updates can appear later in the journey.
